  • In order to reduce the complexity for marking a laser-induced gray image and guarantee the marking speed and marking quality,the gray image is divided into different layers using bit-plane concept in image processing.Different laser energy is used to mark different layers.The gray image is induced by energy overlap from multiple layers.This new method was tested and verified on a galvanometer-type laser marking machine.Large number of experiments were carried out.Compared with the traditional methods,the new method can greatly reduce the complexity of high quality laser-induced gray images and guarantee the marking speed and marking quality.Bit-plane method can also be used to laser-induced color images.It plays a significant role in improving the level of laser-induced image.
